Calculate the LCM of 961,719,642,787,728

Given numbers are 961,719,642,787,728

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 961,719,642,787,728 is 127075966685304.

Find LCM of 961,719,642,787,728 with Prime Factorization


2 961, 719, 642, 787, 728
961, 719, 321, 787, 364

Multiply the prime numbers at the bottom and the left side.

2 x 961 x 719 x 321 x 787 x 364 = 127075966685304

Therefore, the lowest common multiple of 961,719,642,787,728 is 127075966685304.

LCM Formula to Find Lowest Common Multiple of 961,719,642,787,728

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

961 x 719 x 642 x 787 x 728 = 254151933370608

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

961 : 1, 31, 961

719 : 1, 719

642 : 1, 2, 3, 6, 107, 214, 321, 642

787 : 1, 787

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,719,642,787,728, is 1.

Now, the common factors can be found like this.

961:31x 31

719:719

642:2x 3x 107

787:787

728:2x 2x 2x 7x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 254151933370608/(1x2)

LCM = 254151933370608/2

LCM = 127075966685304

Thus, we can understand that the LCM of 961,719,642,787,728 is 127075966685304.
